High temperature fatigue characteristics of P/M and hot-forgedW-Re and TZM for X-ray target of CT scanner

The fatigue strengths at 1000 °C of layeredW-Re/TZM, bulkW-Re and bulk TZM for x-ray target materials were successfully evaluated under load-controlled four-point bending by introducing a fatigue failure criterion as twotimes increase of initial compliance. The obtained fatigue strengths at 1000 °C...
